LIQUID AGITATION' COOLER Attorney Patented 18, 1930 CHARLES-J. NAG IJLOF HEBKIMEB, NEW YORK LIQUID AGITQTION COOLER Application filed June 10,

This invention relates to agitators and more particularly to mechanical agitating means for water tobe used in Connection with 'anysubmerged type milk cooler of any cong'ventional type of manufacture. v

The primary object of this invention is, therefore, the rovision of mechanical means, either in e nature of a propeller of any desi operated by any mechanical means an having full revolution such as a pump, ropeller an,

of pad e which has part revolution, in any way mechanically operated in order to set up an agitation or circulation ofwater our rents in an type ofsubmerged cooler.

A still fiirther object of the invention is to control said agitation or current by'the mechanical means above mentioned, by the provision of one or moremechanical agitat mg means laced at various oints inassociation with t e cooler as may desired bythe design or shapp or location of the refrigerating unit, whet er it be mechanical, or as illustrated in the annexed drawing, in the form of a metal container foricej or'like cooling medium. 1 "Tl-fl A still further object of theinvention is to provide, in connection withthe agitating means, a mechanical refrigerating unit, which is preferably in the form of a metal container, especially shaped and designed to control the agitation or water current as before mentioned.

The above and numerous other ob'ects will become apparent during a study 0 the following description taken in connection with the accompanying drawings, wherein:

Figure 1 is a top plan view of a cooler of conventional construction, with my improved cooling means and agitation device associated therewith, the cooler being shown with the cover thereof removed.

Figure 2 is a longitudinal section therethrough.

Figure 3 is a vertical transverse section through the cooler and fully illustrating the design of the cooling medium container.

Figure 4 is a perspective of the coohng medium container. 7

With reference more in detail to the drawworm or by any design 7 1629. Serial No. 369,910.

cordance with the conventional form of cooler cabinet.

The cooler as herein shown is preferably 'of rectangular configuration and of suitable depth so as to receive milk cans or containers 6 as illustrated. The container 5 is preferably opened at its'top and has a bar 7 extend- 1n transversely across the opening, said bar eing fixed at its opposite end to the side wall of the cooler cabinet, in any suitable manner.

Suitable closures or doors 8 are hinged to one side wall of the cooler cabinet as at 9 and 1t'w1ll be noted that when the doors are in closed position, the same are supported by the cross member 7 and adjacent portions of the sides and the end walls of the cooler cabinet. 'It may be well to mention that the cabinet is also suitably lined as at 11, to provide a water tight container.

As illustrated in Figure 4, the ice container is preferably'formed as an elongated troughlike casing of substantially T-shaped formation and comprising the side walls 10, end walls 12 and a bottom w'all13. The container is preferably T-shaped in formation so as to provide the elongated upper ice receiving portion 14 and the relatively shorter lower compartment 15. At their upper edge, the side walls 15 of the containerare flanged as at 16, the flange extending for the full length \of the container and being provided with a plurality of bolt receivingopenings 17. In practice, the ice receiving container is secured to the underface of the cross bar 7, to depend transversely of the cooler cabinet, the

bottom of the ice container terminating in spaced relation and above the bottom of the cooler. Of course, it is to be understood that the ice container is held suspended from the cross member 7 through the medium of bolts or other suitable fastening means fastened through the openings formed in the flanges 16 and through the said cross member 7 in an obvious manner. One end wall of the ice container is preferably provided with an opening 18 to receive piping for the refrigerant units located within the container.

mechamcal refrigerant is disposed within the said contalner. p

In practice, the'cooler chest is filled with water and the milk cans 6 are submerged therein. The water of course is;cooled by the refrigerant within the container, es

cially adapted for that pur ose. In or er' to agitate the water within t e cooler, I provide suitable agitating means herein designated generally by thereference character A. The said agitating means A is supported on a shelf or platform 18 located exteriorly of the casing and supported by brackets 19 fixed in a suitable manner to one wall of the cooler 5 adjacent the bottom of the cooler. A suitable electric motor 22 is su ported on the platform and the armature s aft 23 of the motor extends through the adjacent end wall of-the cooler 5, and to the outer end of said armature shaft is fixed a suitable pro Her 24.

From the fore oing then, it wil be seen that when the coo or is filled with water, the revolving of the propeller 24 will cause an agitation of the water and the water current caused by said agitation will be controlled due to the particular shape of the refrigerant container as is obvious.

The water being caused to flow beneath the container and through the spaces 25 and 26 caused by the depending bottom portion 15 of the re rigerant container the end walls of which due to the specific shape of the container are spaced inwardly from the adjacent side walls of the cooler 5 as illustrated.

From the foregoin then, it will be seen that I have provided a simple and novel means for causing the agitation of the cooled water within the cooler wherebfi which the container is filled wi the desired tem rature.

Even though have herein shownand described the preferred embodiment of the invention and have set forth in detail certain structural elements, it is to be understood that milk with be kept at 2. In a cooler of the character described, a cabinet open at its to a plurali of doors hingedly mounted on e top for c osi the opening, a cross member transversely o the cabinet at the open top of the cabinet, a sub stantially T-shaped trough depending from the cross member, a refrigerant medium located within the trough, and said trough havthe side walls of the cabinet at the top there-' of, an open top refrigerant container secured at its top to said cross member and depending downwardly therefrom within said cabinet,

said container having a relatively elongated upper compartment extending transversely o the cabinet for the full width of the cabinet, and a relatively shorter lower compartment communicating with and depending from said upper compartment, said lower compart-.

ment of said container having the bottom thereof in spaced relation to the bottom of said cabinet, and a motor-driven rotatable agitating memberqarran ed within said cabinet at one end of said ca inet.

In testimony whereof I aflix my signature.

- CHARLES J. NAGLE.

the invention is susce tible to certain changes fully comprehended y the spirit of the mvention as herein described and the scope of the appended claims.

What is claimed is:

. 1. In a cooler of the class described, a cabinet of substantially rectangular confi ration open at one end, hingedly mounted oors for closing the openin an elongated trough located within the ca inet, means for supporting the trough transversely of the cabinet, said trough being of substantially -T-shaped formation and havin its lower end in spaced relation with the ottom of the cabinet, an electric motor dis osed exteriorly of the cabinet, a propeller ocated within the cabinet, and means 0 ratively associating the propeller with e electric motor.
